0.25 Amp Positive

Voltage Regulators

POWER MANAGEMENT

Description

Features

The EZ55Z3L voltage regulators are monolithic integrated

circuits designed for use in applications requiring a well

regulated positive output voltage with low input-to-

output differential voltage requirements.

u External capacitor not required for stability

u Low dropout performance

u Five fixed voltage options: 3.3V, 5V, 9V, 12V, 24V

u Adjustable output down to 1.25V

u Line regulation typically 0.015%

u Load regulation typically 0.1%

Outstanding features include full power usage up to

250mA of load current, internal current limiting and

thermal shutdown. Safe area protection on the die is

also included, providing protection of the series pass

transistor under most operating conditions. TO-92 and

SOT-223 packages are available for cost effective

applications.

Notes:

(1) Specifications are applicable for a power dissipation of 2.5W and are only achievable over a limited range of

V_IN- V_OUT.

(2) Low duty cycle pulse testing with Kelvin connections required. Changes in output voltage due to heating effects

are covered under the specification for thermal regulation.

(3) 30ms pulse.

(4) Bandwidth of 10Hz to 10kHz

(5) 120Hz input ripple, 1 dB less for each volt increase above 3.3V Min.; C_OUT& C_ADJ(for ADJ) = 25µF.
